DRAFT-RIGGING'.

Specification of Letters Iatent.

ppieation tiled November 15, 1912. Serial No. 731,625.

To autom may concern: Reit known that JoHN J. TATUM, a citizen or" the `United States, residing in the city oi"v Baltimore' and State of Maryland, have invented ce1-tain new and luseful Improvein Draft-Rigging@ which the following is a specification.

The object ot my invention is to provide a hood. or, other receptacle. pivoted on the vtroie? and of a draif'tl gear yoke or casing side oi the head and yoke.

3 .is a perspective view of a draft yoie with lmy improved hood attached -thereto. t

Fig. i' is a perspective view Figs. 5,6, 8 and 9 are perspective views ofl Jfoires showing different forms of attaching means.

E i is a perspective view of a yoke and hood showing another form of joint between them.

is a detail viewv of a draw bar. The reference numeral 1 designates a boister, Q an end sill, and 3 the center or draft sills of a ear between which a draft gear 4 with the front and rear followers and 6 are positioned, all of which may be of aniV improved pattern. A

The front ends of the draft yoke or cas- 7 are pii'rwideigl on their outer faces with 8 han` an arcuate bearing face 9 U t as at 10 on a bevel as more U .xiown in Fig. 4f. .The hood 11 is provided with arcuate bearing 12 in its upper and lower front.

edges beveled forwardly and constructed to receive the lugs 8 on thi` yoke whereby the hood is pivotally swung on the forward ends ai the draft yoke or casing. The hood is jorovided with key ways 13 and 14 through which. a key is adapted 'to pass to lock the d the draw bar 16 in said draw bar having a hey way end which registers with of the yoke theA key Ways 13 and 14 of the hood, whereby the draw baris swingingly mounted on the forward end of the dra-ft yoke or casing. The key also passes through the draft sills of the car.

. nF ig. 5 I haveishown the bearing 17 on the yoke or casing as concaved, just the re# verse to that shown in Fig. 4.-. i f

In Fig. 6 I show thebearing in the form l of a vboss ,18 constructed to .engageA a Ihole made in the top andloo'ttom yof thek hood.

In Fig. 7 showthe hood -19fsecuredvto the yoke or casing 2O by means post or rivet 21 at the top and bottom. In this construction l provide an arcuate slot 22 in the top and bottom of the hood through which a pin'23 projects from' the yoke or casing thereby 4limiting the swing of the hood as will be understood. i

My invention provides irec radial or swinging movement of the draw bar of a car Patenten sept. 1v, i918.

without imposing strain or stress on the.

draft rigging or the sistance and permits trains and greater tonnage with inimimum locomotive energy and fuel consumption'.

By my invention I, also reduce rail wear, wheel flange wear, thus giving a greater factor of safety to both life and property. also reduce to a minimum, wear on the coupler and ,on` the draw. bar.

The pivoted swinging hood provides a- Hoxlble carrier or mounting vb ctwcenthe draw bar and the draft gear and 'underfraniing of the car which enables a train tol pass the sharpest curves without reducing thevenraging surfaces between thc bar, and without imposing a shearing strain on the flange of the wheel and keeping uniform bearing on key in the slots ot' the hood. l My invention may he applied to many types of existing draft gears and draw bars without changing the coiistruction thereof, therefore a railroad may adopt my invention without discarding its standard type of draw bar and its standard type 'of draft gear, it being only necessary to pivotally mount the hood on the forward end of the yoke or casing of the draft gear. A

The bolts 24 serve the purpose of main-A taining the yoke arms in place, in the event small to perform this function.

in Fig. 8, I have shown the yokeprovided.

with an integral back follower,

car,Av reduces tr in rev of hauling longer* yoke and draw In Fig.9, the forward ends of the arms are turned outwardly and rearwardly to form bearings for the hood.

In Fig. l0, I have illustrated the draw bar as being provided with a triangular-shaped key way.

As will be seen from the above description,

, when a train equipped with my improved lsists of a'hood and a loop `having two a yoke, a coupler bar the combibar hood pivotally and sli ably lmounted on the for" ward end of said yoke.

4. In a draft rigging for cars, the combination with a yoke, of a hood pivotally and slidably mounted on the forward end of the yoke and means for securing the hood to the draw bar whereby the draw bar has pivotable and slidable movement relative to the lwith elongated l key yoke. ,l

5. In a draft rigging for cars, a casing, a draft gear, hood swingingly and slidablyy mounted on the forward lend of said casing and provided with elongated key ways through its sides.

6. In a draft rigging for cars, a casing for a draft gear, a hood swingingly mounted on the front end of said casing and provided ways through its side walls, a dra-w bar the rear end of which is positioned in said hood, a key way through the rear end of said bar, and a key of width less than the length of the elongated key ways of the hood, whereby the'draw bar and key may move inwardly independently of the casing.

7.In a draft rigging, the combination with a draft goa-r casing, of a hood mounted on the forward end of the casing to move axially and radially of thecasing.

8. The combination with shock absorbing draft devices, of a U-shaped yoke having bearings at its two front ends, a hood of greater dimension than said yoke loosely mounted on theyoke so that it may move lengthwise of the yoke and swing radially thereon, the outward movement of the hood being limited by said bearings.

9. The combination with'shock absorbing draft devices, of a U- shaped yoke having stops at its free ends, a hood slidingly and swingingly mounted on said yoke, and a coupler to which said headl is keyed.

10. In a draft rigging, the combination with a1 yoke strap, of a hollowv head a' draw bar, and a key extending through the draw bar and the sides of the hollow head, said head being` movable axially and radially relatively to the yoke strap when in operati-ve position. y

11; In a draft rigging the combination with shock absorbing draft devices, shaped yoke having stops at its free hood slidingly and swingingly mounted on said yoke, and seats on said yoke to engage said stops when the hood is at the limit of its outward movement, and a coupler to which said head is keyed. 12. In a draft gear, al yoke, means swing` ingly mounted on the forward end of said yoke, and slidably connected to the yoke when in assembled position with the rear end 'of a coupler, a key to enter alined openings in said means and in the rear end of the coupler to secure said means and coupler togetheiya curved bearing on one of the meeting faces of said means and said yoketo permit'of a laterally swinging movement of said means to accommodate the swinging movement of the draw bar.

In testimony whereof I ailiX my signature in'presence of two witnesses.
